The 3299Z-1-104LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications requiring precision resistance adjustment. This model features a 100 kO standard resistance value with ±10% tolerance, infinite resolution, and 25 turns of effective travel for fine-tuning control. The device operates across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watts at 70°C with a maximum voltage of 300 volts. The 3299Z-1-104LF incorporates 100% tin-plated (RoHS-compliant) solderable pins, U.L. 94V-0 flammability rating, and is sealed to MIL-STD-202 humidity standards, making it suitable for demanding applications in instrumentation, signal processing, and industrial control systems where reliable, long-term performance is essential.
